King of New York: Pete Alonso breaks major Mets all-time record 

Later in the bottom of the sixth inning, Alonso hit his 254th home run:

Along with the all-time Mets home run lead, Alonso is also the Mets' single-season home run leader with 53 home runs during the 2019 season.

Strawberry congratulated Alonso on breaking his record:

His home runs on Tuesday were his 27th and 28th of the season. 

It is a big deal for Alonso because there was some doubt this past offseason if he would have a chance to actually set this record. Even though he was close, the uncertainty around his future given his free-agent status created a lot of questions about where he would play. Ultimately, the Mets re-signed him to a two-year, $54 million contract that includes an opt-out clause following the 2025 season. 

That opt-out will again create some uncertainty about his future, but it is pretty clear Alonso still has a lot of power left in his bat. Whether he returns to the Mets or goes somewhere else, he will remain the franchise's greatest home run hitter for the foreseeable future. He is now on top of the record books for the single season and career.
